What Is Fire-Retardant Lumber?

Physical or chemical methods to improve the fire resistance of wood. The purpose is to retard the burning of wood in order to prevent fires or to gain time and quickly eliminate the fires that have occurred. Wood has a high hydrocarbon content and is a flammable material. So far there is no way to keep wood from burning when it comes close to the source of fire. The requirement for wood flame retardant is to reduce the burning rate of wood. Reduce or retard the flame propagation speed and accelerate the charring process of the combustion surface. This is important for industrial sectors such as construction, shipbuilding, and vehicle manufacturing.

The flame retardant mechanism of wood mainly includes covering theory, thermal theory, non-combustible gas dilution theory, free radical capture theory, carbon content increase and volatile matter reduction theory; the flame retardant treatment of wood-based panels is mainly by adding flame retardants and forming boards in the production process. High-pressure treatment is the most important industrialization method. Phosphorus-nitrogen-boron flame retardants represented by FRW flame retardants and BL-environmental flame retardants are still the mainstream of wood flame retardants. The research on the flame retardancy of wood-plastic composites is still in its infancy. Generally, the methods of flame retarding wood fibers and substrates are generally adopted; the development of highly efficient intumescent wood flame retardants and the application of nanotechnology to the manufacture of wood flame retardants to develop flame retardants Multifunctional composite flame retardants with high efficiency, low smoke, low toxicity, and environmental friendliness will be the development direction of flame retardant research fields in the future.
